SPECIFICATION forming part of Letters Patent No. 286,039, dated October2, 1883. I

I Application-filed hl'areh Ill, 1883. (No specimens.) i

Be it known that LTnonms J. LIAYAILL,'Of Reading, in the county ofMiddlesex and Commonwealth of Massachusetts, have invented 'a new anduseful Improvement in VVater-Iroof Cloth for Garments and otherPurposes, which I will designate asfMayalI Oloth,.'of which thefollowing is aspe'cification.

My invention relates more particularly to. cloth usedfor coats, cloaks,hoods, &c., to be worn for the protection of the wearer in rainy,

1 weather, the object of it being to produce a cloth perfectlyimpervious to water, light,- and durable, alid having'the appearance offine woolen goods on the outside; and it consists in treating linen,cotton, woolen, silk, or other suitable woven or knit fabrics in themanner hereinafter described." l

\Vater-proof goods for coats, cloaks, &c., have been heretofore madebycementing a thin sheet of rubber onabacking of cloth, and

afterward curing or vulcanizing the rubber.

Therehas also'been made cloth known as gos-. I

ing by sun heat or by artificial heat, becomes samer water-proof goodsby spreading a coating of rubber dissolved or partially dissolved innaphtha or other solution on thin cotton or linen goods,.-an d thencuring the rubber in the heat of ,the sun or by artificial heat; but myimproved water-proof fabric differs from any water-proof goodsheretofore made in the materials used to make itfimpervions to water,and'in the quality and appearance of the goods when finished;

To make my improved waterproof goods I put 011 one side of a piece ofcotton, linen, or other suitable cloth the thinnest possible coating,which will cover completely the surface of the cloth, of what I callMayall s Fluid Genient'a compound of rubber in the proportion of ei ghtpounds,with gumsh'ellac from onequarter of a pound to two pounds, andgolden sulphuret of antimony, in the form of an impalpable powder, fromfour to eight pounds,

- thoroughly mixed and incorporated together by grinding in arubber-mill, and the compound dissolved in abath of naphtha of abouteight gallons, This cement .is evenly spread upon thecloth by anysuitable means, and at the same time, if there is any surplus quantityof it on the cloth, it is removed. 'lhere isthen sifted upon the wholesurface of thc cloth cov ered with the cement a considerable thicknessof finely-ground wool, fur, silk, or other animal or vegetable fiber,known as flock,

which is engaged by the adhesive quality of thecement until the wholesurfac' of the cement is completely covered by t e flock adhering to it.The loose flock is then brushed off and the cloth passed under apressing-roller,

which embeds the adhering flock in the cement, and to make it certainthat every porfibrous material of which the flock is made will- Thecement-will soon dry, and without our.-

practically indestructible by action of moistnm or the atmosphere, andof such strength and tenacity that the-cloth upon which it is laid isgreatly re-enforced by it.

I am aware that rubber on water-proof goods has been before covered withflock to give the surface an appearance of woven and finished woolengoods; but as the cement' used has been thc'ordinary rubber cement madeof rubber or gutta-percha dissolved in naphtha, without the addition ofshellac and'golden sulphuret of antimony,which I use, its quality hasbeen so inferior in tenacity and durability that/the flock soonwears orfalls off, and garments made of it soon become shabby and disagreeablein appearance, while my improved water-proof cloth can be worn andexposed for years'aud remain fresh and beautiful as when new. 1

As I have made the combining of the mate- 'rials used in w-hatl termMayalls Fluid Jcme'nt, in the manner set forth, the subject of anapplication for a patent on that as a new process, and for the cementproduced as a new product, I do not claim it in this specification, andI do not claim a waterproof cloth made by covering a w oven fabric witha solution of tier-proof cloth made by coating a woven or rubber orgutta-percha; nor do Iclaim a waknitted fabric with Mayallsflujd cement;and ter-proof cloth coated with flock; but upon which an outer coatingof flock is placed I do claim as new'and of my invention and aflixed in'the manner or substantially as 5 1. As a new article of manufacture, awadescribed;
